Monorail change-wheel device researched and designed in this thesis is the core equipment maintenance and the function of monorail change-wheel device is to achieve the separation of vehicle body and bogie, convenient for tire inflation or replacement operations. In this paper, from the general structure of the change-wheel device, according to the mechanical structure and environment on the electronic control system requirements, I list the control system solutions and determine the general scheme of electronic control system of change-wheel device system through a comparative analysis. The control system is introduced emphatically. Meanwhile, the paper contains a stress analysis of lifting platform endured partial load to explore the reasons and determinants of its level error, and puts forward electro-hydraulic proportional hydraulic synchronization scheme. The paper establishes a mathematical model of synchronous control system and discusses the reasons to simplify the system model. Using the computer simulation of mathematical model，the paper analysis of the system model from the theoretical. Finally, the paper describes the entire electronic control system to take the security measures and anti-jamming design. The electronic control system of monorail change-wheel device researched a
